properties:
  pre-delay:
    type: int
    description: |
      Delay in nanoseconds inserted between chip select assert to the first
      clock edge. If not set, no additional delay is inserted.

  post-delay:
    type: int
    description: |
      Delay in nanoseconds inserted between the last clock edge to the chip
      select deassert. If not set, no additional delay is inserted.

  frame-delay:
    type: int
    description: |
      Delay in nanoseconds inserted between data frames when chip select is
      asserted and the EOF flag is set. If not set, no additional delay is
      inserted.

  transfer-delay:
    type: int
    description: |
      Delay in nanoseconds inserted between transfers when chip select is
      deasserted. If not set, no additional delay is inserted.

  def-char:
    type: int
